Subsistence Resource Access and Environmental Conditions in Alaska, 2016-2017

Citizen-collected photos and descriptions from nine rural Alaskan communities document how environmental conditions impacted travel and access to subsistence resources. Observations cover a 17-month period from February 2016 to June 2017. The dataset includes a derived sensitivity metric based on participants' adaptive capacity to these conditions.

Use Cases

• Analyze the relationship between specific environmental conditions and travel safety for harvesters based on participant descriptions.
• Study the frequency and perceived extent of environmental changes based on community observations.
• Model adaptive capacity to environmental variability using the derived sensitivity metric.
• Visualize and classify environmental challenges to subsistence access based on the photo collection.

Strengths

• Data includes a derived sensitivity metric incorporating participant adaptive capacity.
• Observations span a defined 17-month period from February 2016 to June 2017.
• Covers nine distinct communities within the Yukon River basin of Interior Alaska.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific communities and time period.
